Application of GPR method for detection of structural failures
Křepelka, Jan ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
This Bachelor thesis deals with the non-destructive testing, which enable researches of failures in concrete inner structure. In the theoretical part of the thesis, selected methods are described based on their principles. Specific possibilities of use, abilities and limits are based on the method’s principle. In the practical part, the thesis focuses on Ground Penetrating Radar with the usage of a new multi-frequency scanning technology. The measurements took place with commonly used Ground Penetrating Radar Hilti PS 1000 X Scan and also with newly available Ground Penetrating Radar Proceq GPR Live. Not only the measurement results of model solids were compared, but also of real bridge construction.

Diagnostics of selected bridge structure
Jedlička, Lukáš ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
This thesis deals with building survey of bridge register number 43-011 located near Česká. The part of thesis is literary reaserch dealing with system of management and cotrol of road bridges, precast bridge contructions made with DS-C type girgers and about general diagnostical methods. The practical section contains of in situ diagnostical survey and bridge inspection, laboratory evaluation and comparision, load bearing capacity calculation and suggestion of potencional technical precautions.

Methods used in diagnosis of masonry structures
Vrtal, Roman ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
The thesis is focused on testing methods used in diagnosis of masonry structures. It describes their implementation and evaluation, as well the tools needed for their realization and also their advantages and disadvantages. The aim of the thesis is to compare most commonly used testing methods and to describe their application in practical example of static load test of brick pillar.

Diagnostics of the construction and technical condition of the granary building
Velát, Matěj ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
The bachelor's thesis deals with the diagnostics of the historic granary building and the conceptual design of the reconstruction for further use. The thesis focuses on the history of similar buildings especially in the Czech lands and on the historical development of the building. The practical part of the thesis denies the course and results of the preliminary inspection of the structure and the failures found which are further addressed in more detail in terms of their nature. The presumed reason for the occurrence of failures the state of failures their influence on the construction and an outline of the risk analysis resulting from the failures are determined. Furthermore, a proposal for a methodology of detailed object diagnostics is based on the results of a preliminary inspection. According to the information about the object found during the diagnostics two ideological proposals for further possible use of the object are processed, including the necessary construction modifications.

Diagnostic research of the family house
David, Jan ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This bachelor’s thesis deals with technical construction research of the family house which is located in 15 Horní Street in Brno. Technical construction research had to be made, due to the change of the owner of the house and to determine the status for possible reconstruction. Research includes description of the methodology of diagnostic work on building and evaluation of research with results and draft measures. The results consider the state of structure and status of its component parts.

The use of ultrasonic testing in construction
Sztulová, Petra ; Komárková, Tereza (referee) ; Láník, Jaromír (advisor)
The thesis is divided into two parts. The first part is focused on the use of ultrasonic methods in building practice. Explains here how ultrasound works. The second part focuses on the possibility of anchoring. It describes what is chemical, mechanical anchoring. It deals with the tensile testing additionally mounted chemical anchors Hilti. Primarily focuses on what happens if it fails to comply with the correct technological procedure when installing chemical anchors.

Effect of type and dose of scattered reinforcement on selected properties of concrete.
Láníková, Lucie ; Schmid, Pavel (referee) ; Láník, Jaromír (advisor)
The Master’s thesis is focused on the research influence the dose and type of scattered reinforcement in a reference concrete on physical and mechanical properties of the resulting composite. The investigated properties of composite belongs compressive strength, tensile strength in the flexural and tensile strength in the transverse, static modulus of elasticity in compressive strength, dynamic modulus of elasticity determined using NDT tests. The reference concrete mixture is certified as structural concrete of the class, which is commonly used on construction sites.

Survey and assessment of reinforced concrete bridge construction
Šnédar, Jaroslav ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
The aim of this thesis is to evaluate the real condition of reinforced concrete beam bridge located in Brno Jundrov. In order to evaluate this condition, there was made the main bridge inspection. Subsequently, a number of diagnostic methods were used, such as hardness tests, concrete stress strenght, ultrasonic pulse method, including their evaluation. In terms of the main inspection, the condition of construction of the bridge was evaluated as V - bad. We found out that the concrete from which the bridge is built of is in very good condition. The problem, however, is the condition of the reinforcement located on the bridge. Based on its condition there must be expected lifespan within the next 5-10 years.
